this feels like it should be straight forward but I'm having no luck. I want to let the end user select a check box that says "Subscribe to our mailing list." If they select the check box they get put in the "Subscribed" user group.
My checkbox is appearing on the front end sign up form. In field management the Option is set to: Subscribe=38 (38 being the "Subscribed" group ID)
On this same page I've got a hidden field that assigns users to multiple groups when they sign up. This is working.
